melanotic sarcoma may occur as metastatic from an original melano-sarcomatous tumor of the skin or eyeball.
The tumor, a melanotic sarcoma, was about the size of a small walnut, and located in the small of the back of an elderly lady.
Squamous epithelioma and melanotic cancer are the forms met with.
Hip lameness may also be provoked by melanotic or other tumors.
The melanotic cancer contains abundant pigment, melanin, within its cells.
The melanotic matter is easily effaced by washing, while the other is removed with difficulty.
The black pigment of the cells of melanotic tumors, also called melanin, is not to be directly traced to the hmoglobin.
